The convention I have used in my graphs is to list these sets of powers horizontally & left-to-right. Like this list of Powers-of-Two. (The consecutive positive integers above the list give both the value to be raised to the power, as well as the ordination of an element in the list. Which is to say, the fifth power of two is five to the power of two. How convenient!
)
Another convention I have is to pause & look over a result.
I spy with my little eye that the ending digits of the Perfect Squares (Powers-of-Two) have a repeating ten-digit-long pattern:
{1 4 9 6 5 6 9 4 1 0 }
I also spy that the pattern does not use/contain the digits 2, 3, 7, or 8.
That's another break.
